THE LIFE AND DEATH OF A LAKE
HTML-код
- Опубликовано: 27 сен 2024
- An underwater exploration of how a lake slowly turns into a forest through a series of three trophic stages, the oligotrophic stage, the mesotrophic stage, and the eutrophic stage. This transition from an aquatic ecosystem into a terrestrial ecosystem is known as aquatic succession. These changes are set in motion by an increase in the nutrient levels in the lake and a build up of the sediment layer on the lakebed. This process is also known as hydrosere succession or lentic succession.

A great video, here's more money for the African butterfly fish project
Wow, thank you so much! I am in your debt. 😁
50K is very close now..........Wonderful video as always :)
Yes! Thank you!
Thank you for this Dave. I can’t think of a better way to get back to myself, after spending a month in hospital, than watching this awesome video of your beautiful lake. You always transport me into the place you are filming, and I love what you do.🖤🇨🇦
Hello once again. I was worried about you, since you didn't comment on my last video. I really missed your beautiful spirit and your supportive comments. I'm so happy that you're back, and I wish you a speedy recovery. Stay well my friend. ❤❤❤
@@TheDave333 Thank you Dave, I didn’t mean to worry you, but it took being in hospital to make me miss commenting. I will seek out what I missed, and they will receive my full attention. I am working on getting back to my usual self…I currently weigh 94 pounds after a complete metabolic crash, so I know where to start. I will be more watchful for early signs after this little adventure. It means a lot that you noticed my absence…💖🖤🇨🇦
Great shots
Thanks
This lake is a paradise!
Yes it is!
thanks, Dave
You're very welcome, thanks for watching the video.
WoW ! Another great video 😮 thank you for those explanations 👍👍
You are very welcome my friend, thank you for always taking the time to watch them and leave a comment. 😁
Fish are amazing!
Yes they are!
That was great!
Thank you. 😁
Of all the underwater lake videos you have, all of them are my favorite! Cool! Great! Awesome! 😀
Wow, thanks! 😁
Thank you for another amazing video. You have touched an interesting topic and maybe we would need to help prolong the life of lakes to preserve diversity in a non-invasive way.
In some cases, yes, but I'm also a firm believer that mother nature doesn't need our help. She just needs us to stop interfering with her process. . . 😁
I learn so much from your videos. Thank you.
You are so welcome! Thank you for watching them! 😁
Another great video
Thank you
Great video buddy much love from Long Island,NY!
Thank you so much!
Fascinating video as per usual. Would make a great introduction to students in a biology lesson 🤓👍
Definitely! Thank you so much. 😁
Love your videos
Thank you
I've recently got into the aquarium hobby, and accepted a volunteer position with my county conservation board. I can't wait to go back to school and finally study biology. Your videos are so inspiring. Thank you.
That's awesome! Biology is a wonderful subject. I'm so happy that my videos have inspired you. 😁🦈🐟🦐🦠
Thank you once again! Another one for the algo.
My pleasure!
How can I stop the aging process of a small lake?
You can slow it down by limiting the amount of nutrients going into the lake. (dead leaves, trees, invasive aquatic plants, runoff from the surrounding landscape, erosion of the lake shore. etc. )
Beautifully done video and very informative. I live next to a pond created about 1983 so it's about 40 years old and a little over 1/2 acre. Created to handle run-off in the neighborhood along with another larger pond across the street that is connected via pipe under the street. So incredibly full of wildlife. Had our first tree fall into the pond early this year after some intense rain and wind. Not thinking at all about the pond's aging process, I decided to leave the tree where it fell as it completely prevents neighborhood kids and families from casting their fishing lines toward the left side of the pond (our property) which in the past has snagged many a tree and killed some green herons that get caught in line left behind. Also figured it would be great for the bass/bluegills/carp etc for feeding and breeding. Have really enjoyed seeing the full trunk covered with turtles basking on it every sunny day. Did not at all consider the affect it would have on the sediment and build up at the bottom as it is a relatively shallow body of water. Also, the back corner of the pond is on our property and that is where the wind blows all the fallen leaves and debris - it is very shallow and floor gets gradually deeper. It occurs to me now that we might clean up maybe 1/4 of the sediment and leaves each year just from that corner to help our pond stay a little younger, similar to what I do for my fishtank. Not sure - maybe I shouldn't do anything different. No floating plants or emergent plants to be found on the pond though there are patchens in the connected pond across the street - uncertain what submerged growth might be in the pond. Never seen a fish die-off here though I've seen it elsewhere. Lots to consider as I really do enjoy looking out of my kitchen window and seeing bass jump, and standing at the edge and seeing black pools of baby catfish at the surface, plus the added excitement of beautiful ducks that stop over to feed each winter. Lots of new information to consider from this video!
Thanks for watching the video, and I'm glad that it got you thinking more about the changes that occur in your little slice of heaven. I'd love to have something like that outside my window. . . And like you, I am also not a fan of discarded fishing line. . .
Great informative video
Was wondering what those cotton like things at the bottom of the lake are? Algae?
Dead filamentous algae. When you try to touch them, you can't even feel them. They just disappear between my fingers.
Im trying to reach semi eutrophic conditions in my tanks it seems, what a great video mate, very informative, cheers from Scotland 🏴
Thanks for watching the video. A mature (semi-eutrophic) tank is the way to go! Time and patience my friend. 😁
Nice video. Cant eait for hillstream loach tank :)
Edit:WOW i did NOT know that. Really interesting.
Glad you enjoyed! Still waiting for my hill stream loaches to produce babies.
Wow, thats a hard challenge. Hope for the best.
Me too. . .
Question: did someone have platy fish agression? And NOT platy to platy agression, and to other fish.
The tank its 15 gallons and has corydoras rasboras and 3 New platies. I have added them about 5 hours ago and sometimes pecks The rasboras. I have NEVER see a platy fish being agressive towards another fish species.Unfortunately i cant get him back to The fish store.
What should i do?
(edit) only one its agressive, it is NOT a xipho or molly.
There's one in every crowd! It might just be settling down and establishing a pecking order with the other types of fish. Once it feels secure in its new home it might mellow out. Be sure that it's not food related aggression by making sure that there's enough food for everyone. Hopefully, it will settle down after a while.
can it be possible to extend the lifespan of a lake by boosting the population of decomposers? Id hope it would allow the decaying material to continue cycling back into the living plant biomass instead of accruing at the lakes bottom.
Great question. The lake has lots of decomposers, but those plants will still die and eventually end up filling in the lake. Biomass will still accumulate, the only way to reverse it is to remove the built up material from the lake. Biomass is still constantly being added to the lake from the surrounding area, such as in the form of falling leaves and trees from the shoreline. Material is added faster than it breaks down.
Eye-catching video + plenty information about lake life cycle. Throphy stages are similar to life stages of any living organism - youth, adult and old. All chemical changes and life itself are in fact ruled by microorganisms, especially bacteria.
So true my friend. . . You are wise beyond your years. 🐟🦐🦠
Thank you ! I like biology from early childhood, and, like kind of such "meditations".
I've loved biology and nature from a very young age as well. My first love was reptiles, but then I found fish. . . 🦈🐟🦐
the lake is alive…
It is, and I love it. . .
Hooray! you're a fellow New Englander How many East Massachusetts. You do not have a Boston accent as far as I can tell But you might have like no sound down east main either maybe Vermont West Vermont southern Vermont connecticut western Connecticut Edison New Yorker either like a New Yorker I'm confused where are you from I'm not trying to track you down I just like I like to place accents I'm an accent of all. my favorite actions are from like alabama the Kentucky Irish and Scottish and Welsh and English I do like German and Japanese accidents as well. so I just I like to place roughly where people are from you said you're from New England but I can't place where in New England. embassy says that we know how to track you down if I wanted to and I don't. you could be middle middle state or upstate Maine possibly because my grandmother was from down East Main your Kenny Bunkport and she had a very distinctive accent
I'm originally, form the United States Virgin Islands, but now I live in Western Mass. I've had people tell me I sound like I'm from California. I've lived in a lot of different places over the years. . .
I wonder how Sergeant Slackjaw and his fellow bluegill are doing.
Spawning season is over and they're trying to bulk up for the long winter ahead.
Outstanding video footage and great information presented in an easy to understand format. The Dave is my favorite aquatic videographer.
Wow, thanks! I've made a few videos about this lake where I go into details on most of the animals seen in this video. ( past subjects include - largemouth bass, chain pickerel, yellow bullhead, bluegill sunfish, Eastern Newt, common snapping turtle, painted turtle, and freshwater sponges) At some point, I will make a compilation video about everything in the lake (plants and animals) where I will name everything on screen. So, look for that one in the near future, because there's still a lot more to see. Thanks for watching the video and have a spectacular day. 😁
@@TheDave333 Thanks! I will watch for the upcoming video! until then, keep them coming, you put out great content!
Thank you. 😁
You should go to Merrymeeting Lake someday.
You're right I should!
absolutely love your videos
Thank you so much
@@TheDave333 Me too! They're amazing!
Great Video 👍
Thanks 👍
Great knowledge, thx for all the information 👍😊
You're very welcome, and thanks for watching the video. 😁
There's a couple ponds near me that have been treated very poorly and only get cleaned when someone points it out. Panfish are fighting and overrunning the bass populations. People litter extremely bad, possible poaching etc.
I fish but I love marine biology. I'm catch and release only as I love seeing the fish and learning about each and every single one. So much I've started a student club at school to promote the act of, teaching of fishing and marine conservation at the same time
I think it's great that you've started a student club to promote the conservation and understanding of water and the life within it. It's a shame how little regard some people have for the natural world, and water is such an important natural resource you would think that people would have a lot more respect for it. Keep up the good work. 🦈🐟🦐🦠 🐠❤
A lovely video! Unfortunately, it goes against my evil scheme to turn half the continental United States into a backyard pond for my private estate, so I shall now be plotting to stop aquatic succession.
Best of luck with that. I'd love a backyard pond on a private estate.
I just found your channel and am binge watching your videos. Your voice is very soothing
That's so awesome. Thank you so much for watching my videos!
So, Dave, you really love it when I say something about saltwater fish?
I don't know if love is the right word, but you tend to introduce me to fish and cetaceans that I've never heard of before.
And I do love the water, so maybe???
It is a great educational video!
Amazing content
Thank you so much! 😁
Have you heard of the MathScience Innovation Center? It's located in Richmond, Virginia. I went there in 2012 for the slippery, slimy odd pets summer camp. I went there again in 2013 for the James River summer camp. My sister also went there in 2013 for slippery, slimy odd pets.
Hi Chi, I've never heard of the center, but it looks like a great place to learn. I was contacted by company based in Richmond called Explore Learning that creates STEM courses for K - 12 students. They're creating a course designed around the American Shad in the James River and Chesapeake Bay and they wanted to buy some of my Shad footage for the course. I wonder if these two places are somehow connected? I love slippery and slimy pets.
we love you dave
Bobby the great lives here😢
Parts of him might be there in the great circle of life.
In this video we can see amazing fishes known from your older videos. Perhaps I see superstar lady bass, actually I am thinking about name for her 🤔
Let me know if you think of a good name. I'd love to hear it.
Dave, I'm actually looking forward to river videos coming soon. I mean it. I really am!
Awesome! Me too! You won't be disappointed. 😁
amazing video as always, wonder how this process plays out in lakes over a million years old
Everything seems to run in cycles, and a million years is a very long time. The drifting of continents can create lakes as well. 😁
do rivers evolve in a similar fashion?
@badabing3391
What a great question!!! Rivers do evolve over time, but in a slightly different fashion. Sediment is picked up in high current areas and transported by the river, where it is then deposited in areas where the water slows. In low gradient streams, this moving sediment can cause rivers to meander and change their course. When a river bends, one side of the river takes away sediment (the cut bank/ erosion) and the other side of the river gathers sediment (the depositional bank). There two sides of the river cause it to move and change as sediment is transported from one area to another.
High gradient mountain streams tend to stay in the same fairly straight river channel, but over time they erode the bed rock beneath them forming steep valleys or canyons along the way. Think Grand Canyon. This wearing away of the bedrock causes the stream gradient to lessen over time. And a high flow steep gradient mountain stream can eventually become a low gradient slow flowing river that passes through steep canyon walls that were worn away by millions of years of erosion.
Rivers are also subjected to periodic floods that scour the river bed and remove the built up sediment. This deepens some sections of the river, erodes river banks and moves sediment from one place to the other changing the course and the depth of the river. It looks like I have a new video topic!!!
@TheDave333 Thank you for your answer, it seems like rivers then tend to be more stable ecosystems than lakes given their ability to prevent drying up entirely and simply change course and move around the sediment buildup. Does this means that it would be rare to see much speciation in the shorter lived lakes as opposed to rivers? Or can there be significant differentiation in lakes depending on the stage or other factors involved? Like lake baikal or the african rift lakes, tho these seem exceptional in size and age.
Lake Baikal and the rift lakes of Africa are very old aquatic ecosystems, so there's been a lot of time for the fish there to diversify into new species that fill specific niches. The stability of standing bodies of water certainly helps. However, there's actually a remarkable degree of species diversity in rivers, especially in brackish areas near coast.
In fact, freshwater fish evolved from saltwater species that began to move inland along coastal streams. So, this meeting of the freshwater and the ocean provides an abundance of different transitional creatures that are slowly evolving from one type of animal into another. Coastal mangrove swamps can host a wide variety of creatures seen nowhere else. . . Change forces creatures to adapt / evolve, or they'll die, so it can actually increase speciation.
TheDave333,
When preparing the river video, do some research into how wolves changed the course of a river (in Yellowstone National Park).
While it is a good example of what happens when any species of animal goes extinct; it's also a sped up version of how rivers change and evolve (or devolve) over time.
See if any of that story might be of use to you.
And yes... wolves actually changed the course of a river.
Your videos are wonderful
Thank you very much!
What if the dave made high qualtiy salt water fish videos?
That would be awesome too, but at the moment, I only have freshwater tanks. 😁
